communication broken after eufy update fw to 1.1.2

[createeve]

All was working until I upgraded firmware in Robovac 30c from 1.1.1 to 1.1.2 I've checked key and uuid in the adb - still the same as before update. From the original app all is working as before.

HA gives this output: Traceback (most recent call last): File "/root/.homeassistant/custom_components/eufy_vacuum/tuya.py", line 533, in _async_handle_message response_data = await self.reader.readuntil(MAGIC_SUFFIX_BYTES) File "/usr/lib64/python3.6/asyncio/streams.py", line 578, in readuntil raise IncompleteReadError(chunk, None) asyncio.streams.IncompleteReadError: 0 bytes read on a total of None expected bytes

Yuuuup they've gone and changed the message encryption. This is going to take some digging...

[mitchellrj]

codetheweb/tuyapi#175 should provide the necessary info if they get there first. The Eufy Tuya API has been upgraded to version 3.3 from 3.1. The pre-encryption is all wrapped up in a native, compiled library now.

Looks like they cracked it

[Netfreak25]

Is it working now on 1.1.2? Anyone tried it yet?

[mitchellrj]

I'm taking a look at this now, I'll post further updates as I make progress. Thanks for the update @6a61636b.

[mitchellrj]

I've added the compatibility for Tuya 3.3, but it doesn't seem to work. I'll keep poking it, but it's possible Eufy are doing something a little different.

[raulfunkie]

Any updates on this? I was planning on purchasing a Robotic 15C MAX but found this and now I'm having second thoughts :(.

[mitchellrj]

Sorry @raulfunkie, I've not had the time lately and I'm not likely to for 2 months or more.

[mitchellrj]

Alright, I think I've cracked it. Try using the code from the tuya_3_3 branch. Once I've got another confirmation, I'll merge it.

[raulfunkie]

Playing with it. Seems like there's communication now but it fails to complete the demo. What happens to me is as follows:

• Robovac turns on.
• Robovac turns vacuum on.
• Start to clean
• 1s after, it stops
• It stays there.

This is the log I'm getting:

[mitchellrj]

That's the full extent of the demo, were you expecting it to do anything further, or do any of the steps you listed fail?

[raulfunkie]

Correct me If I'm wrong but shouldn't it:

• waits 30 seconds (cleans for 30s or stops in the spot for 30s?)
• Send the device home
• wait 10s
• Disconnects and exit.

The demo starts, but the vacuum only "cleans" for 1sec, then suddenly disconnects and does nothing. It does not return home (no matter how much time I wait).

[mitchellrj]

The demo used to do that, but I changed it at some point, I'm not sure why. https://github.com/mitchellrj/eufy_robovac/commit/aa063a43a34eb867043d09654f1f87d4190a7949#diff-e845259df144dbc96b1cea727a8f0ed9

I'll take that as confirmation and get this merged and closed 👍

@raulfunkie Does this now work for you on your 15C MAX?
